IBOILER-WASHING- DEVICE.

Application led J' une 2l To all whom t may concern.'

Be it `known that I, JOSEPH E. HIXON, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and uselul Improvements in Boiler-Tashing Devices; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable vothers skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in ay boiler' washing device for washing out yiue boilers.

The main object of the invention is to provide a simple and eiticient portable device easily inserted and operated within a flue boiler for washing the tops. of the lues thereof to remove mud and scale deposited thereon.

A further object or' 'the invention is to provide a device of the character defined which is equipped with adjustable nozzles adapted to be fixed in position to correspond to the relative elevations of the tops et horizontal series or rows of lues of the boiler so as to simultaneously wash mud and scale from the tops of the several of said rows simultaneously, and in which said nozzles are maintained always at the proper levels during travel of the device.

The invention consists in the Jfeatures or' construction and combinations of parts hereinater fully described and particularly claimed.

In the accompanying drawings illustrating a suitable embodiment of the invention:

Figure -lis a transverse section of a Hue boiler showing the boiler-washing device positioned therein tor washing the same.

Fig. -2- is a central longitudinal section of a washing device constructed in accordance with the invention, the same being partly broken away.

Fig. 3 is a. fragmentary detail section on the line 3-3 of Fig. -2.

Fig. 4ris a fragmentary detail section on the line ll-t of Fig. 2.

Fig. -5- is an end elevation of a crosshead shown at the top of Fig. -2-- Fig. -6- is an end elevation of the discharge nozzle shown in Fig. 4-.

Referring now to said drawings: A indicates a supply pipe provided contiguous to its upper end with two dia-metrically op- Specicaton of Letters Patent.

posed hollow arms B .provided with perfora-- At its lower end said pipe A terminates in an elbow F to which a hose may be readily attached'to connect said pipe with a source of supply of water under pressure. Between the elbow F and the cross-head, consisting of the arms B, said pipe A is provided with a plurality of longitudinal slots Cr. Mounted within said pipe A are short pipe sections H, which are telescopically movable therein and are longer than vthe slots Cr. Each of said pipe sections II is provided with diametrically opposed threaded openings adapted to receive the threaded shanks 'of discharge nozzles I. Each of the latter is provided with a plurality of perfora'tions J disposed in the same horizontal plane and at angles to each other. The threaded shanks of said nozzles I are adapted toreceive lock-nuts K ot greater width than the slots G, and which are adapted to bear upon the outer wall of the pipe A at opposite sides of each of the slots Gr to securely clamp the pipe sections H in place. This arrangement enables the elevation or relative positions of the pairs of nozzles I to be changed and varied to accord with the distance separating the tops of the several horizontal rows of fines in the boiler from each other. The perforations C are arranged similarly to the perforations J, as shown in Fig. -3-, so that each of the nozzles I and pipes B will project several streams of water horizontally in different directions. This arrangement causes the water jet-s to wash sediment and scale from the end portions of the iues contiguous to the end plates of the boiler and from the latter.

As shown in Fig. -1- the pipe A is inserted through the manhole L, the cross-head consisting of the arms B, being at this time vertically disposed. While in this position the pipe A is turned through an arc of ninety degrees and elevated until the cross-head is disposed above the elevation of the uppermost row of flues M within the boiler, and

is then turned on its own axis through an arc of ninety degrees whereupon said cross-head will rest upon the upper faces of two of said upper lues M. rlhe nozzles I will now be positioned so that the perforations J therein will be disposed in the planes of the respective rows of fiues M at lower elevations. The elbow F is then connected with a hose or pipe connected with a source of supply of water under high pressure, and while the water is being discharged from said nozzles and pipes B the said pipe A is moved longitudinally from end to end of the boiler while suspended from said flues. As

f shown in' said Fig. -1- the pipe A is of less length than the depth of the entire series of horizontal rows of iues M. After being disposed at the elevation shown in full lines in Fig. -lthe elbow F may be disconnected from the pipe or hose and the pipe A then lowered to the position shown in dotted lines in Fig. -1-, and thereupon reconnected with the hose or pipe for continuing the washing of the lues which have not been sufiiciently washed while the pipe A is positioned as shown in full lines in said figure. It is obvious, of course, that the pipe A may be made of any convenient length desired.

While l have shown the preferred embodiment of my invention in the accompanying drawings, it will be obvious, of course, that said embodiment may be changed and varied in details of construction without departing from the invention as defined in the appended claims.

l claim asv my invention:

1. A boiler` washer comprising a water i supply pipe, a cross-head contiguous to one 2. A boiler washer including a water supply pipe adapted to be inserted between a pair of vertical rows of lues, and equipped with means for effecting connection between said pipe and a source of water under pressure, a plurality of pairs of dischargenozzles carried by said pipe at various points between the ends thereof; and means for varying the relative positions of the several pairs of nozzles longitudinally of said pipe.

3. A boiler washer including a water supply pipe adapted to be inserted between a pair of vertical rows of tlues, and equipped with means for effecting connection between said ypipe and a source of water under pressure, a plurality of pairs of diametrically opposed longitudinal slots in said pipe, a plurality of pipe sections of greater length than said slots telescopically movable within said pipe for closing said slots, nozzles projecting through said slots and mounted in said pipesections, and means for locking said sections against movement in said pipe.
